PURPOSE Childrens Cancer Group (CCG) protocol 2861 was designed to test the feasibility of aggressively timed induction therapy followed by autologous or allogeneic bone marrow transplantation (BMT) as the sole postremission therapy for newly diagnosed children with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). PATIENTS AND METHODS Between April 1988 and October 1989, 142 patients were eligible for study. All patients entered received a timing-intensive five-drug induction of dexamethasone, cytarabine (Ara-C), thioguanine, etoposide, and daunorubicin (DCTER) over 4 days with a second cycle administered after 6 days of rest, irrespective of hematologic status at that time. Most patients subsequently received a second two-cycle induction course. Those who achieved remission were eligible for bone marrow ablative therapy with busulfan and cyclophosphamide, followed by 4-hydroperoxy-cyclophosphamide (4-HC)-purged autologous or allogeneic BMT rescue. RESULTS One hundred eight (76%) patients achieved remission: 19 (13%) died of complications of the leukemia and/or chemotherapy, and 15 (11%) failed to achieve remission. Seventy-four patients subsequently underwent BMT with either autologous (n = 58) or allogeneic (n = 16) rescue. For patients who received autologous rescue with 4-HC-purged grafts, the actuarial disease-free survival (DFS) rate at 3 years from the day of transplant is 51%, compared with 55% for patients who received allogeneic grafts (P = .92). At 3 years, the overall actuarial survival rate for all 142 patients entered on this study is 45%, with an event-free survival (EFS) rate of 37%. Adverse prognostic factors for outcome included an elevated WBC count or the presence of CNS leukemia at the time of AML diagnosis. CONCLUSION Results suggest that aggressively timed induction therapy followed by marrow ablation and BMT rescue with either autologous or allogeneic grafts for children with newly diagnosed AML or MDS is both feasible and effective.

Abstract Abstract 3602 Background: AML in elderly patients is associated with very poor prognosis. The best treatment option for this group of patients is not established, yet. The intensity of treatment depends on performance status and comorbidities. The previous PALG AML study showed that addition of cladribine (2CdA) to conventional induction therapy; especially in patients above 40 yrs, is associated with better outcome (Ho3owiecki 2004). Based on this observation we designed a study addressed to newly diagnosed AML patients above 60 yrs old, who were fit enough to intensive treatment. Aim: To verify whether addition of 2CdA has an impact to clinical outcome in newly diagnosed AML patients older than 60 years old. Methods: From October 2004 to November 2011, 178 patients from 16 hematological PALG centers were randomly assigned to DA induction therapy consisting of daunorubicine (DNR) 45mg/m2, intravenously (iv), day 1–3 and cytarabine (AraC) 100 mg/m2, iv, day 1–7 (DA) or DA with addition of 2CdA 5mg/m2, iv, day 1–5 (DAC). Patients, who achieved complete remission (CR), received one course of consolidation with mitoxantron 6mg/m2 iv day1–2 and AraC 100mg/m2 iv day 1–5, followed by six cycles of maintenance consisting of (DNR 30mg/m2 iv day 1–2 with AraC 100mg/m2 sc day 1–5 and tioguanine 100mg/m2, p.o., twice day, day 1–5 with AraC 100mg/m2 s.c. day 1–5, alternately). Response criteria were determined according to revised recommendations of the International Working Group for Diagnosis, Standardization of Response Criteria, Treatment Outcomes, and Reporting Standards for Therapeutic Trials in Acute Myeloid Leukemia (Chesson 2003). Statistical analysis: Pairwise comparisons between patient characteristics were performed by the Mann-Whitney U-test for continuous variables and by χ2-statistics or Fisher's exact test for categorical variable. The Kaplan-Meier estimates of survival were calculated and compared using the log-rank test. For multivariate analysis, the Cox proportional hazard regression model was applied. P values < 0.05 were considered significant. Results: 88 pts with median age 66 yrs (range 60–79 yrs) were randomized to DA and 90 pts with median age 64 yrs (range 60–79 yrs) was enrolled to DAC schema. The both groups were comparable in terms of age, sex, performance status, white blood cell count, hemoglobin level, platelets count, tumor burden parameters, cytogenetic, between the both groups. The overall CR rate was 38%. In DA and DAC groups CR was achieved in 33% and 43% pts, respectively (p=0.12). However, in patients under 65 yrs the trend towards higher CR rate in DAC arm than DA group was observed (47% vs. 29%, p=0.09). In pts above 65 yrs the CR rate was comparable (39% vs. 38%, p=0.8). The efficacy and hematological toxicity in DA and DAC groups was similar (Table 1). Also no statistical significant differences in non-hematological toxicity were observed (data not shown). Early deaths in DA and DAC did not differ significantly. Median overall survival (OS) in DA and DAC arm was also similar in both groups (Table 1). In proportional hazard Cox analysis only age under 65yo, CR achievement and WBC above 100G/L were important for better OS (p=0.02, p<0.001 and p=0.09). The presence of dysplastic changes, karyotype, LDH, number of bone marrow blasts did not influenced OS. Conclusions: Our data suggest that prolonged overall survival can be achieved in elderly AML patients mainly till 65yrs. Intensive therapy, especially in patients older than 65yrs, may be associated with high number of complications what results withdrawing from intensive treatment protocol. Hematological and non-hematological toxicity of DA and DAC schema is comparable, however higher CR rate in DAC group in patient till 65yrs may suggest, that addition of 2CdA to DA does not increase toxicity and may be a treatment option in this patient population.

7073 Background: The goal of induction chemotherapy in acute myeloid leukemia (AML) is complete remission with restoration of normal bone marrow. If residual leukemia is present after the first course of induction therapy, patients receive a second course identical to the first or receive a non-cross resistant antileukemic regimen. Methods: In a retrospective study of adult patients with newly-diagnosed AML treated at the University of Pittsburgh Cancer Institute between December 2002 and May 2008, we evaluated the efficacy and toxicity of mitoxantrone (10 mg/m2/d) and etoposide (100 mg/m2/d), both administered intravenously within 5 days as second course therapy of patients not responding to first-course induction therapy with cytarabine and idarubicin. Univariate and multivariate associations between patient characteristics and complete response (CR) were assessed by logistic regression, with overall- and relapse-free survival estimated by Kaplan-Meier analysis. Results: 74 AML patients (mean age 56 years, range: 18–73 years) completed treatment with etoposide and mitoxantrone; 29 (39%) achieved CR. Lower CR rate was associated with unfavorable cytogenetic risk status at diagnosis and higher percent blasts prior to treatment with mitoxantrone and etoposide. Ten (14%) patients died due to infectious complications. No grade 3 or 4 hepatic toxicities were observed. One patient developed grade 3 cardiac toxicity. Median duration of neutrophil recovery following therapy in patients achieving CR was 29 days. Median overall survival was 9.0 months (95% CI 5.8–14.9 months). The 29 patients who achieved CR received postremission therapy: 16 of these eventually relapsed, while 4 others died without evidence of relapse. Median duration of relapse-free survival in these 29 patients was 11.0 months (95% CI: 9.0–19.3 months). Conclusions: Our study suggests that the combination of etoposide and mitoxantorne is an active and well-tolerated regimen as second-course therapy in newly diagnosed AML patients who have persistent leukemia after a first course of induction therapy with cytarabine and idarubicin. No significant financial relationships to disclose.

Abstract Clonogenic cells from 41 children with newly diagnosed acute myeloid leukemia (AML) were tested in vitro for their sensitivity to cytarabine (Ara-C) and daunorubicin (DNR). The findings were then compared with the patients' responses to induction chemotherapy that uniformly included Ara-C and DNR. Light-density marrow cells were incubated with either or both drugs for one hour and cultured over leukocyte feeder layers; clusters and colonies were scored on days 7, 10, and 14. Only the percentage of cell kill in the presence of 1.8 mumol/L DNR was significantly associated with responses to induction therapy: median of 45% (range, 0% to 98%) for patients achieving complete remission v 16% (range, 4% to 23%) for nonresponders (P = .007). The relationship between clonogenic cell kill less than or equal to 23% and clinical responses was striking. Of the 11 evaluable patients with in vitro findings in this category, ten either failed induction therapy or relapsed within 1 year after attaining remission. Kaplan-Meier analysis of relapse-free survival times indicated longer durations of remission for patients whose blast cells showed increased sensitivity in vitro to Ara-C alone, DNR alone, or a combination of the two agents. Seven of 11 patients with cell kills of greater than or equal to 49% in the presence of 1.25 mumol/L Ara-C remain free of leukemia, compared with only one of 12 whose cells were less sensitive to the drug (P = .006). We conclude that the in vitro sensitivity of clonogenic leukemic progenitors to DNR and Ara-C correlates with treatment outcome in children with newly diagnosed AML.
